    A y intercept is the y value when x = 0 The x intercept is the x value when y = 0 plug in 0 for x and solve for y, that's the y intercept plug in 0 for y and solve for x, that's the x intercept

    so its 3(0)-9(0)=-27?

    This is our equation: 3x − 9y = -27 Y intercept = 3(0) - 9y = -27 since anything ultiplied by 0 is 0 we have -9y = -27 -27/-9= y-intercept X intercept = 3x - 9(0) = -27 3x=-27 -27/3 = x-intercept
